Fourth Level Assessment- Aquatic Habitat Rehabilitation Plan

Culvert Remediation

Work to remediate culverts identified as barriers to fish passage has been undertaken by the Petitcodiac Watershed Alliance as part of their Broken Brooks project between 2014 and 2022 (Table 7). At several sites more than one form of culvert remediation has been employed, in some cases during the same year, and in other cases over the course of several years.

Debris removal has been the most common culvert remediation method- used at five of the eight culverts worked on within the Pollett River watershed. Where needed, doing so is certainly useful and relatively simple compared to options such as building rock weirs or installing outflow chutes.

The need to do so however is partially a function of time as the presence of debris, woody and otherwise is a result of accumulation, and / or the growth of vegetation. Consequently, no doubt sites where such work was warranted in 2014, such as C-012 (Figure 30) and C-041 (Figure 31) probably need to be revisited by 2022.
